IODIN SOLUTION.

To all whom it may concern:

Be it lmown that I, JOHN WEMER, a citizen of the United States, and aresident of the city, county, and State of New York, United States ofAmerica, have invented certain new and useful Improvements in- IodinSolutions, of which the following is a specification.

My'invention relates to a novel method for producing iodin in solutionin a chemically available and functionally active form, and to the,combination of chemicals having free iodin therein in solution obtainedby this method as a new article of manufacture, or a substance notheretofore known in the arts.

I have discovered that crystalline iodin may be dissolved in a solutionof tannin and glycerin without changing its chemical characteristics orproperties. According to my invention crystalline iodinis first reducedmechanically to a fine powder. One part of this powder is then placed ina solution of four parts of tannin to sixteen parts of glycerin in aclosed vessel and The iodin will become entirely dissolved therebywithout changing or affecting its chemical roperties. A perfect solutionis thus obtained which is stable, has no sediments, and will notprecipitate.

A syrup is made of white rock candy and pure water, referably of such r0ortions that there be seven and one al pounds olfhtihge rock candy toeach-gallon of the syrup. which 'I have already described. I have usedthis in the proportions of ten parts of the syrup to one part of theiodin solution. The syrup acts as a preservative of the iodin solutionand as it has no ingredients or ele ments whichattack the iodin, thelatter refree.

- 1 I iodin or the functions which it 1s capable o performin aredesirable but can not be obtained sa ely. By my novel method this wantis supplied. The solution, or the solution with its'preservative s rupis free from salts, contains no freeacid and is not irritant norinjurious.

What I claim is.

5. The herein described method of obtainin free iodin in solution whichcomprises re ucing crystalline iodin to a powder, pla'cing it in aclosedvessel with gllycerite of 7 5 tannic acid and causing it to 0moved throu h said liquid. I

6. he herein described method of obtaining free iodin in solution whichcomprises reducing crystalline iodin to a powder, placing one part ofsaid powder in a-closed vessel with four parts of tannin and sixteenparts of lycerm, a 'tating said vessel until the powcfir is disso iodinsolution a and water.
